Search through all partitions using REST API?

I'm attempting to query for a virtual server in the TEST partition using this command:

/mgmt/tm/ltm/virtual/myvirtual

which defaults to:

/mgmt/tm/ltm/virtual/Common/myvirtual

this displays nothing.

I can use this command and my virtual server will show up:

/mgmt/tm/ltm/virtual/~TEST~myvirtual

Is there a way to query all partitions if I don't where the virtual server is located? For example:

/mgmt/tm/ltm/virtual/~ALL~myvirtual

Is it necessary to query for the list of partitions then step through each one?
